4.7.1 Performance. The performance parameters of 3.3.1
through 3.3.10 shall be demonstrated either manually or using a
contractor designed, Government-approved, automatic test fixture
simulating the conditions and making the measurements of
providing a visual indication of a PASS or FAIL condition. Test
shall be conducted before ESS testing, and after completion of
The performance test shall verify that each of
the ESS testing.
the following CCA functional characteristics conform to the
requirements of 3.3.1 through 3.3.10 inclusive. Output Power
should be verified at 18.0 to 30.0 VDC input voltage in
accordance with TABLE I and 3.3.2 and:
4.7.1.1 Antenna Power output voltaqe. 26 VDC minimum and 55
VDC maximum while output current is 1A maximum and ripple 2 Vp-p
maximum.
4.7.1.2 +12V voltaqe. +11.4 VDC to +12.6 VDC, with 80 +/- 4
ohm resistive load and ripple of 200 mVp-p maximum.
4.7.1.3 -12V voltage. -12.6 VDC to -11.4 VDC, with 80 +/- 4
ohm resistive load and ripple of 200 mVp-p maximum.
+5 voltaqe.
4.75 to 5.25 VDC, with 2.5 +/- 0.1 ohm
4.7.1.4
resistive load and ripple of 100 mVp-p maximum.
167 +/- 8
4.7.1.5
-5V voltaqe.
-5.5 VDc to -4.5 VDC, with
ohm resistive load and ripple of 200 mVp-p maximum.
4.7.1.6 Reverse Voltaqe Protection. Reverse voltage
protection on power input lines shall be verified by applying a
reverse voltage supply to the CCA, and verify that the input
current is less than 0.01 Ampere.
4.7.1.7 Power. Line Monitor, Lamp Power and Relay Power
shall be tested for short circuit between pins 12, 13, 31, 10 of
P4 . Output voltages shall be verified on pins 12, 31 of P4 as
follows:
Output voltaae
Input Power
16.7 +/- 0.5 Volts
18.0 + .1 Volts
22.4 +/- 0.5 Volts
24.0 + .1 Volts
28.5 +/- 0.5 Volts
30.0 - .1 volts
4.7.1.8 Short circuit Protection. Short circuit protection
shall be tested by shorting each of the outputs (+5V, -5V, +12V
and -12V only) for at least 30 seconds and then verify that the
supply has recovered, by measuring the output voltage according
to 4.7.1.1.
4.7.2 Environmental
stress screeninq.
